COFFEE URN.

Application filed September 1, 1926. Serial No. 133,053.

This invention relates to improvements in coffee urns and has as itsgeneral object to provide a coffee urn which will possess materialadvantages over the urns which are in common use. Coffee urns, asordinarily constructed, embody a container for the coffee to'which heatis directly applied and the coffee infusion is maintained at a highlyele vated degree of temperature fora long period of time. I have foundthat where coffee is subjected to heat for several hours itgraduallyloses its color and strength and becomes unpalatable. Therefore, thepresent invention has as its primary object to provide a coffee urn soconstructed that the coffee drawn therefrom will possess maximumstrength and a rich color, due to 'the fact that provision is made fordelivering the coffee hot and yet not maintaining the same constantly ata high degree of temperature.

Another object of the invention is to provide a coffee urn soconstructed that by its use, a material saving in the consumption ofcoffee will be effected and the coffee delivered therefrom will be in ahighly desirable condition for consumption.

In the accompanying drawings:

Figure 1 is a vertical sectional view through the coffee urn embodyingthe invention.

Figure 2 is a horizontal sectional view taken substantially on the line2-2 of Figure 1, looking in the direction indicated by the arrows.

The urn embodying the invention comprises a hot water container which isindicated in general by the numeral 1 and which preferably comprises acylindrical body 2 of sheet metal or any other material found suitablefor the purpose and supported in an elevated position by legs 3 toaccommodate a heater 4 through the medium of which water within thecontainer is maintained at an elevated degree of temperature. A watergauge 5 is preferably mounted upon the ex terior of the chamber 1 andwithin the chamber there is arranged a pipe coil 6, the upper end ofwhich extends through the wall of the chamber and is provided with areceiving funnel 7 which serves a purpose to be presently explained, thelower end of the coil being extended through the wall of the chambernear the bottom thereof and arranged to deliver coffee into a cup heldtherebelow.

The container or chamber 1 is open at its top and is provided with aseating shoulder 9, and a coffee reservoir 10 is disposed at its closedbottom upon this shoulder and in addition to its closed bottom, which isindicated by the numeral 11, is provided with a false bottom 12, thewall of the reservoir between the bottom 11 and false bottom 12 beingformed with ventilating openings which arelindicated by the numeral 13and which provide for the circulation of air between the main and falsebottoms so as to dissipate heat rising from the heating chamber 1. Thecoffee container has a delivery pipe 1 1 connected at one end 'to itsbottom 12 and this pipe leads through the wall of the chamber betweenthe bottom 11 and the false bottom 12 and communicates with a manuallyc0ntrolled.cut-off valve 15, the delivery end of the casing of which ispositioned directly above the funnel 7, so that by manipulating thevalve, coffee may be delivered from the reservoir 10 into the funnel andthence into the pipe coil 6.

The coffee reservoir 10 is provided at its open top with an annular seat16 in which is engaged the margin of a foraminous bag 17 to contain thepulverized coffee and this bag is retained in place by a resilient splitk ring 18 which engages the said margin and confines the same in theseat 16. The reservoir is provided with a removable cover 19 so thatcoffee, already prepared, may be introduced into the reservoir, thefluid and dreg constituents of the coffee being both introduced into thereservoir and the fluid constituent draining through the bag 17, leavingthe dregs in the said bag. A level gauge 20 is preferably provided uponthe exterior of the reservoir 10 so that the quantity of fluid coffeetherein may be readily ascertained.

The base member 21 of the container 1 is of greater diameter than theupper body thereof, as shown clearly in Fig. 1, and at the margin of thebase member are one or more overhanging lugs. Encircling the lower endof the container and supported by the base member is a rack consistingof a flat annulus having openings 24 each adapted to receive a cup, asindicated at 24. A base ring 25, connected with'the rack by feet 26,carries the rack and engages under the lugs 22 so that it will be heldto the base member 21 thereby and may rotate about the cylindrical bodyof the container. The proniittedto remain therein until delivered frontatmospheric;temperature and L therefore main! vision of this rackfacilitates "the filling of several cups in succession and, bymaintainin; a plurality of cups in proximity to the container, raisesthe temperature of thecups so that chilling of the coffee by contacttherewith is avoided. I l I From the foregoing description of the1nvention, it will be obser'i ed that; unlike the connnonpractice,coflee alr eady preparedis introduced into the conta ner 10 andp'erthespout 15 into the cioil dibeing nearly at t aining its full strength andcolor, It will e se' den ml he" for in de cr ptionthgit by opening thevalve antiperh coil 6. the I i ns tla ntly h' a'ted fa nd will issue holt i'ror'n the coil so tliatfa supply hot c'ofic e s always availah liwit-lio'ut the disadvantages attend 1 11;; the maintenance of the"coffee at a'const'antly elevated teinperatu're.

Having thus described the invention, I claim 5 1. In a coffee urn, aheatin chamber, a coil therein, a 1 coffee reservoir supported upon thesaid cliai riloef, an air ventilated "chamber between the heatingchamber and the reservoir, and means mounted in the air Ventilated'cl'iamlier for delivering coffee from the reservoir to the coil, I
